篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Python处理Excel中数据3 (按照班级筛选数据_把数据保存在一个文件的各个sheet中)相关的知识,希望对你有一定的参考价值。

一,源数据的载入

需求: 1. 按照班级筛选

    2. 把筛选出来的数据分别保存在一个文件的各个sheet中

 

二,代码编写

 1 import pandas as pd
 2 import os
 3 import time
 4 import openpyxl
 5 # 1.加载Excel源数据
 6 path = R"C:\\Users\\Administrator\\python处理Excel数据\\20200113\\按照班级分离文件.xlsx"
 7 workbook = openpyxl.load_workbook(path)
 8 sheet_names = workbook.sheetnames
 9 sheet1 = workbook[sheet_names[0]]
10 
11 # 2. 读取Excel sheet1中的所有数据
12 allDatas = []
13 for row in sheet1.rows:
14     lines = [cell.value for cell in row]
15     allDatas.append(lines)
16 
17 #划分班级
18 title = []
19 class1 = []
20 class2 = []
21 class3 = []
22 class4 = []
23 class5 = []
24 
25 for i in allDatas:
26     if i[0] == "1":
27         class1.append(i)
28     elif i[0] == "2":
29         class2.append(i)
30     elif i[0] == "3":
31         class3.append(i)
32     elif i[0] == "4":
33         class4.append(i)
34     elif i[0] == "5":
35         class5.append(i)
36     else:
37         title.append(i)
38 
39 #文件保存路径
40 path = R"C:\\\\Users\\\\Administrator\\\\python处理Excel数据\\\\20200225"
41 
42 if not os.path.exists(path):
43     os.mkdir(path)
44     print("目录创建成功")
45 else:
46     print("目录已经存在")
47 # 工作表名字
48 date_rand = time.strftime("%Y-%m-%d", time.localtime())
49 file_name = path + \'\\%s.xlsx\' % date_rand
50 writer = pd.ExcelWriter(file_name)
51 
52 #生成新文件的各个sheet.并添加title
53 sheet1 = pd.DataFrame(class1,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"])
54 sheet2 = pd.DataFrame(class2,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"])
55 sheet3 = pd.DataFrame(class3,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"])
56 sheet4 = pd.DataFrame(class4,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"])
57 sheet5 = pd.DataFrame(class5,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"])
58 
59 #写入数据到各个sheet中并指定列行标
60 sheet1.to_excel(writer,"sheet1",startcol=0,index=False)
61 sheet2.to_excel(writer,"sheet2",startcol=0,index=False)
62 sheet3.to_excel(writer,"sheet3",startcol=0,index=False)
63 sheet4.to_excel(writer,"sheet4",startcol=0,index=False)
64 sheet5.to_excel(writer,"sheet5",startcol=0,index=False)
65 
66 # 将缓存写入工作表
67 writer.save()
68 print("数据写入成功!")
